1 . A delivery vehicle for delivery of consignments to different sites along a delivery route, with a loading space comprising a shelf system for shelves holding consignments, characterized in that the shelf system is configured to receive shelves in a plurality of storage positions for provision of the shelves and in at least one extraction position for extraction of consignments from the shelves, and that the shelf system has at least one adjustment device for adjusting the shelves of the shelf system between several storage positions and the at least one extraction position;

wherein the shelf system has a grid with an empty space without a shelf in the manner of a shifting puzzle and according to which a shelf of the shelf system adjacent to the empty space is provided so as to be displaceable in a longitudinal direction or in a transverse direction with respect to the grid onto the empty space;

wherein the at least one adjustment device is configured to adjust at least one of the shelves, the adjustment device has a guide device comprising a rail system arranged above the shelves for guiding the shelves in the shelf system between several storage positions and the extraction position, wherein rails of the guide device are connected to each other by a series of T-pieces and crossings and the shelves are moveable along individual ones of the rails in two, three or four directions depending on a position of the shelves at which the shelves are connected to the guiding device;

wherein the at least one adjustment device is configured to adjust the shelves in any storage position in the longitudinal direction and in the transverse direction along the rails of the rail system into any adjacent storage position in the shelf system;

wherein the shelves have castors or rollers to be moved in the longitudinal direction and in the traverse direction standing on the floor of the delivery vehicle; and

wherein a locking device is assigned at least to individual shelves for locking the respective shelves in the storage position.

2 . The delivery vehicle according to claim 1 , wherein at least one of:

the storage positions of the shelf system are arranged in rows running parallel or perpendicular to each other,

the number of shelves of the shelf system corresponds at most, preferably at least substantially, to the number of storage positions, or

the shelves of the shelf system are configured at least substantially the same.

3 . The delivery vehicle according to claim 1 , characterized in that a control device is provided for controlling the adjustment device for adjusting the shelves relative to each other and preferably for adjusting the shelf with the next consignment to be extracted from a storage position to the extraction position.

4 . The delivery vehicle according to claim 1 , characterized in that the shelves have segments for receiving consignments and preferably that the shelves have carrier elements which are removable from the shelves, for receiving consignments.

5 . The delivery vehicle according to claim 1 , characterized in that an extraction device is provided, preferably comprising a robot arm, for extraction of a consignment from the shelf present in the extraction position, and preferably that the extraction device is provided for introduction of a consignment into the shelf present in the extraction position.

6 . The delivery vehicle according to claim 1 , characterized in that the locking device is assigned to individual shelves, preferably to each shelf, for locking the respective shelf in the storage position and preferably in the extraction position.

7 . The delivery vehicle according to claim 1 , wherein at least one of the shelf system has at least one receiving device for receiving shelves or an output device for output of shelves, preferably with consignments, of the shelf system.

8 . The delivery vehicle according to claim 1 , wherein the at least one delivery device is configured to adjust each shelf of the shelf system into each storage position and into the extraction position.

9 . A method for delivery of consignments to different sites along a delivery route with a delivery vehicle according to claim 1 , with a loading space comprising a shelf system with shelves for receiving consignments in a plurality of storage positions and at least one extraction position, the method comprising the steps of:

adjusting the shelf with the next consignment to be delivered via an adjustment device from a storage position into the extraction position, and

adjusting other shelves of the shelf system such that the other shelves, for adjustment of the one shelf into the extraction position, clear at least one storage position and preferably the extraction position;

wherein the at least one adjustment device is configured to adjust the other shelves step by step one after the other in different directions in order to adjust the shelf with the next consignment to be delivered into the extraction position;

wherein the shelf system has a grid with an empty space without a shelf in the manner of a shifting puzzle and according to which a shelf of the shelf system adjacent to the empty space is provided so as to be displaceable in the longitudinal direction or in the transverse direction with respect to the grid onto the empty space;

wherein the at least one adjustment device is configured to adjust the shelves in any storage position in the longitudinal direction and in the transverse direction into any adjacent storage position in the shelf system.

10 . The method according to claim 9 , wherein in particular all shelves are adjusted by means of the adjustment device in stages successively in different directions, preferably along and transversely to the delivery vehicle, in order to adjust the respective shelf with the next consignment to be delivered into the extraction position.

11 . The method according to claim 9 ,

clearing at least one storage position by the adjustment of shelves, and

adjusting at least one of the shelf with the next consignment to be extracted or another shelf into the at least one cleared storage position, and

in which, preferably, the steps described above of clearing and occupying storage positions are carried out repeatedly.

12 . The method according to claim 9 , further comprising:

determining with a control device, depending on at least the arrangement of the shelf with the next consignment to be extracted, a suitable sequence of adjustment of shelves for adjusting the shelf containing the next consignment to be extracted into the extraction position, and

wherein the adjustment of the shelves by the adjustment device takes place according to the sequence of adjustment of shelves determined by the control device.

13 . The method according to claim 9 , further comprising:

receiving, before driving the delivery route, shelves carrying consignments in the shelf system, and

outputting shelves of the shelf system before driving the delivery route.

14 . The method according to claim 9 ,

extracting with an extraction device, preferably with a robot arm extracts a consignment from the shelf arranged in the extraction position and delivering the consignment towards the outside relative to the delivery vehicle, and

wherein, preferably, the extraction device receives a consignment from the outside and transfers it to the shelf arranged in the extraction position.
